Brian,email sent and yes, the hair grows out to keep me warm during winter months, professor Xavier and his team helped with a successful hair retraction/extension gene mutation

in all serious though, that's my bf's forearms in some of the shots (the hairy armed ones), his reach is a heck of a lot longer than mine

bina,my man has never posted on here, he only sees any of these posts when I link it to him, he's got his own car (and forums) to enjoy...the coupe be mine!

Does it look like the strut bar will clear the intake. I was thinking of getting it but some are saying that it sits too high and there might be some clearance issues.
